mhash — Computes hash
此函数自 PHP 8.1.0 起弃用。强烈建议不要应用此特性。
$algo, string $data, ?string $key = null): string|false
mhash() applies a hash function specified by
algo to the data.
algo
The hash ID. One of the MHASH_hashname constants.
dataThe user input, as a string.
keyIf specified, the function will return the resulting HMAC instead. HMAC is keyed hashing for message authentication, or simply a message digest that depends on the specified key. Not all algorithms supported in mhash can be used in HMAC mode.
Returns the resulting hash (also called digest) or HMAC as a string, or
false on error.
